Rand doesn't unless you want him to hunt down the generals and so forth one at a time. Besides, every bit of info so far states that the regime is a popular one. The people support the invasion of the Seanchan and are behing their leaders.

No, the politics of the situation is "stop trying to conquer my homeland and my allies while I am trying to save us from the Dark One, you included!" He was not even trying to stop them for good, just get them to stop until the Dark One is taken care of.

And every attempt from within Germany was ignored or rebuffed by the Allies.
And the Seanchan are Martians. Their imported colonists and probably a good many of their conquered subjects would follow Galgan if Fortuona was killed, and applaud his continuation of the same policies.

We did. We basically fought the war in the interests of the Soviet Union, which did not include an existing Germany.

But that's the case here. And that definition is facile and dishonest, because it presumes opposition to their leader's policies on the soldiers' parts, when in fact, the Seanchan soldiers are, for the most part, co-conspirators.

So what? None of this has ANY bearing on the Seanchan OR the Borderlanders. By every indicator available, the common soldiers of the Borderlands and the Seanchan soldiers and local auxiliaries are all supporters and willing followers of their leaders. They go along with the plans and acts that justify killing their leaders, but they get off scot-free simply because they were not consulted about the decision which they nevertheless agree with and support?
